TreeTableView

装填数据

Data data1 = new Data("张三", 20, true);  
Data data2 = new Data("李四", 30, false);  
Data data3 = new Data("王五", 40, true);  
Data data4 = new Data("赵六", 50, false);  
Data data5 = new Data("钱七", 60, true);  
Data data6 = new Data("孙八", 70, false);  
Data data7 = new Data("周九", 80, true);  
TreeItem<Data> root = new TreeItem<>(data1);  
TreeItem<Data> item2 = new TreeItem<>(data2);  
TreeItem<Data> item3 = new TreeItem<>(data3);  
TreeItem<Data> item4 = new TreeItem<>(data4);  
TreeItem<Data> item5 = new TreeItem<>(data5);  
TreeItem<Data> item6 = new TreeItem<>(data6);  
TreeItem<Data> item7 = new TreeItem<>(data7);  
root.getChildren().addAll(item2, item3, item4);  
item2.getChildren().addAll(item5, item6);  
item3.getChildren().addAll(item7);  
root.setExpanded(true);  
item2.setExpanded(true);  
item3.setExpanded(true);

设置TreeTableView

TreeTableView<Data> view = new TreeTableView<>();  
view.setLayoutX(100);  
view.setLayoutY(100);  
view.setRoot(root);  
view.setPrefWidth(300);  
// 平分列宽  
view.setColumnResizePolicy(TreeTableView.CONSTRAINED_RESIZE_POLICY);  
// 设置多选  
view.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);  
// 设置单元格可选中  
view.getSelectionModel().setCellSelectionEnabled(true);

设置列

TreeTableColumn<Data, String> nameCol = new TreeTableColumn<>("姓名");  
TreeTableColumn<Data, Number> ageCol = new TreeTableColumn<>("年龄");  
TreeTableColumn<Data, Boolean> maleCol = new TreeTableColumn<>("布尔");  
nameCol.setCellValueFactory(new TreeItemPropertyValueFactory<>("name"));  
ageCol.setCellValueFactory(new TreeItemPropertyValueFactory<>("age"));  
maleCol.setCellValueFactory(new TreeItemPropertyValueFactory<>("male"));  
// 加载列  
view.getColumns().addAll(nameCol, ageCol, maleCol);

事件监听

// 行单选事件  
view.getSelectionModel().selectedItemProperty().addListener((observable, oldValue, newValue) -> {  
    System.out.println("选中的行：" + newValue.getValue().getName());  
});  
// 行多选事件  
view.getSelectionModel().getSelectedItems().addListener((InvalidationListener) observable -> {  
    ObservableList<TreeItem<Data>> list = (ObservableList<TreeItem<Data>>) observable;  
    System.out.printf("-----------选中的行数：%d----------------", list.size());  
    list.forEach(System.out::println);  
});  
// 单元格多选事件  
view.getSelectionModel().getSelectedCells().addListener((InvalidationListener) observable -> {  
    ObservableList<TreeTablePosition<Data, ?>> list = (ObservableList<TreeTablePosition<Data, ?>>) observable;  
    System.out.printf("-----------选中的单元格数：%d----------------\n", list.size());  
    list.forEach(item -> {  
        // 获取每一个单元格  
        Object data = item.getTableColumn().getCellData(item.getRow());  
        System.out.printf("(%d,%d):%s\n", item.getRow(), item.getColumn(), data.toString());  
    });  
});
